Thermal power plant slag sorting

Thermal power plant slag sorting

Slag is one of the waste generated in thermal power plants, and if not treated in a timely manner, it can have adverse effects on the environment and human health. The slag separation technology can separate the useful substances in the slag, providing the possibility for Recycling and reuse. This article will introduce the operational steps and technical principles of slag sorting in thermal power plants.

1、 Principle of slag sorting technology

The slag sorting technology mainly uses physical methods to sort the slag and separate useful substances from it. Common sorting methods include heavy medium sorting, magnetic sorting, wind sorting, etc.

Heavy medium separation is the use of media with different densities to separate useful substances from the slag. Magnetic separation uses magnetic materials to separate the magnetic substances in the slag. Wind separation uses airflow to separate light and heavy substances from the slag.

2、 Operating steps for slag sorting

1. Collection and storage of slag

In thermal power plants, slag is generated in the boiler, so it is necessary to set up a slag collector below the boiler to collect the slag. The collected slag needs to be stored in a dedicated slag storage bin.

2. Pretreatment of slag

The pretreatment of slag is to facilitate subsequent sorting work. Generally speaking, slag needs to undergo steps such as crushing and screening to break down large blocks of material in the slag into small pieces, facilitating subsequent sorting.

3. Separation of slag

Select an appropriate sorting method based on the physical properties of the slag for sorting. Generally speaking, heavy medium separation is suitable for materials with large density difference in slag; Magnetic separation is suitable for situations where slag contains magnetic substances; Wind separation is suitable for situations where there is a significant difference between light and heavy substances in slag.

4. Recycling and utilization of sorted substances

The materials obtained after sorting need to be recycled and utilized. Generally speaking, useful substances in slag include metals, glass, ceramics, etc. These substances can be recycled to reduce resource waste and environmental pollution.

3、 Application of slag sorting technology in the field of environmental protection

The slag sorting technology has a wide range of applications in the field of environmental protection. By using slag sorting technology, useful substances in slag can be separated, reducing resource waste and environmental pollution. At the same time, the sorted material can be recycled, saving energy and reducing pollution.

In addition, slag sorting technology can also be applied to the treatment of urban waste. By separating useful substances from urban garbage, the amount of garbage can be reduced, resources can be saved, and environmental pollution caused by garbage can also be reduced.

Summary

The slag sorting technology is a very promising technology. Through the slag separation technology, the useful substances in the slag can be separated, providing the possibility for Recycling and reuse. At the same time, slag sorting technology can also be applied to the treatment of urban garbage, reducing the pollution of garbage to the environment.
